Immune Mediated Thrombocytopenia


Immune Mediated Thrombocytopenia

IMT is a condition in which blood cells called “platelets” are unable to help repair small tears in blood vessels. Basically, when there are tears in the blood vessels, bruising occurs. Platelets help in the healing process of smaller tears. Seemingly, the dog’s immune system views the platelets as a foreign organism and attacks them. This disorder can become severe and if it does, can lead to internal bleeding in the spinal cord and the brain which can be fatal.


Symptoms

Due to the lack of platelets, the dog may experience sudden bruising. These bruises are typically large; however they consist of many smaller bruises. Typically, these types of bruises are noticeable on the gums of the dog, the whites of the eyes, and the stomach area. Other symptoms include:

  • Bloody nose
  • Blood in the stool
  • Blood in the urine


Causes

To date, the primary cause of this disease has not been determined. Some other notable causes include:

  • Toxins
  • Bacterial infections
  • Genetics


Treatment and Prevention

In order to treat this disorder, there are certain immune-suppressing medications that can be taken such as:

  • Prednisone
  • Azathioprine
Surgically removing the spleen is also an option. Be sure to consult with your vet in order to determine the best solution to this problem. The best prevention method is to simply not breed carriers of this disease.
